Hi, I just bought a 2004 beetle, it did not come with an owners manual. Is there a way to retrieve the radio code from a working radio? I need to disconnect my battery to try to reset my door control module (need to disconnect the battery for approx. 30-90 minutes) and I'm afraid when I do this my radio is going to go into safe mode. I looked in the trunk and I found a sticker, with my vin# and the color code for the car, not sure if the radio pin# is on this sticker also. Any help will be apprciated! Thanks!
